DIY KIT Fully separation HIFI Tone preamp kit base on UK NAD preamplifier
Note: this list is for a kit. all the parts need solder by yourself.
Reference to the UK NAD3020 amplifier tone part, using double-sided thickened gold-plated PCB (substrate 2MM, copper foil thickness 75U, not 50U comparable) design, hifi components assembled, the circuit using single-ended amplification, High magnification (HFE300 +): 2SA992 / 2SC1845 audio dedicated pipe. The latter two pairs of A1145 / C2705 audio dedicated to the tube, the regulator circuit using a new LM317 / 337 high-precision low-noise regulator IC, a new revision to upgrade ELNA blue robe electrolysis, Taiwan potentiometer. The biggest feature of this tone is to adjust the high and low frequency, IF almost no change, low-frequency stretch! High frequency slim not harsh! Sound mellow is very nice! The effect is not comparable to the op amp pitch.
High bass adjustment range: bass + -15DB, treble + -10DB
Potentiometer distance from left to right: 40MM, 58MM
Size: 138 * 81MM
Voltage: AC: 24V - 0V - 24V
Package include: NAD preamp kit X 1
